Pilot MBR to treat refinery wastewater

The Petroleum Environmental Research Forum (PERF) has selected Siemens Water Technologies to
provide a Petro membrane bioreactor (MBR) pilot unit to test the viability of the technology in
treating refinery wastewater.

This will be one of the first operational full-scale MBR processes for treating refinery wastewater
in the world.

The results of this pilot testing will be used to determine the effectiveness and
robustness of MBR treatment compared with conventional biological treatment on this type of
wastewater. The commercially-sized pilot unit will run for 6-9 months at a PERF site in Baton
Rouge, Louisiana, USA.

Specifically designed to meet the goals of petroleum and chemical industry operators
with flexibility and ease of operation, the Petro MBR system combines an activated sludge
biological treatment process with an innovative membrane filtration system. A novel fluid
renewal process evenly distributes liquid, solids and air within the membrane modules in the
system.

The system is ideally suited to a wide range of refinery, petrochemical and production
water treatment applications including water reuse, upgrades, retrofits and compliance-driven
projects.
